LOOSE-LEAF BINDER.

Application filed March 14, 1922. Serial No. 543,569.

of the ring type, that is, one having curved or ring-like fasteners rather than the straight or post type.

A common fault with binders of this type is that the leaves catch or bind upon.

the rings and become torn; also they tend to spread out along the rings and prevent the covers of the binder from fully closmg. I overcome this trouble in the present invention by using a plurality of narrow filling strips between each cover and the stack of leaves whereby to retain the leaves in compact form at their inner edges and cause them to occupy the front portion of the rings.

One form which my invention may assume is exemplified in the following description and illustrated in the accompanying drawings, in which- Fig. 1 shows a sectional view of a loose leaf binder in open position and fitted with filling strips according to my invention.

Fig. 2 shows a sectional view of the same in closed position; and

Fig. 3 shows a perspective view of one of the filling strips.

For the purposes of illustration, I show a conventional type of binder comprising covers, 10, back plate 11 and fastening rings 12. These rings are split at 13 and are held in closed position by any suitable form of spring means. Loose leaves 14 having holding holes 15 at their inner margins are arranged upon the rings, being freely slidable thereon. Between each cover and the stack of leaves I arrange a plurality of filling strips 16, which are in the form of narrow strips of comparatively heavy paper having reinforced eyelets 17 to fit upon the fas tening rings 12.

These strips serve to force the loose leaves into compact position at their inner edges,

ent is:

as best illustrated in Fig. 2. It 111 be Seen that the loose leaves are caused to occupy a position at the front of the fastening rings so that the back covers may be closed fiat. VVltllOllt these filling strips the leaves tend to climb back upon the rings and prevent-the cover from closing. Also without the filling strips the leaves tendto get out of alinement andcatch or bind upon the rings, with danger of tearing or mutilating the leaves. It will be noted that the strips are so narrow as not to interfere with the closing posed edgewise with relation to the covers. The numberof strips 16 can be varied to suit the conditions ofthe book, that is to of the covers even whenthe strips are dissay, where the book contains a relatively small number of leaves, then a larger number of filling, strips should be used than would be the case where the book is fairly well filled with leaves.

Having thus described myinvention, what I claim and desireto secure by Letters Pat- 1. A. loose leaf binder comprising covers, a back strip, fastening rings on the back strip to receive and retain loose leaves in place between the covers and a plurality of separately removable filling strips arranged upon the rings between each cover and stack of leaves for the purpose mentioned. I

2. A loose leaf binder comprising covers, a back strip, fastening rings on the back strip movable apart to receive loose leaves in place thereon and a plurality of narrow strips formed with reinforced eyelets to fit over the rings and arranged between each cover and stack of leaves to force the leaves forwardly upon the rings and com press their inner edges.

3. A loose leaf binder comprising covers,

place between the covers, and a relatively narrow filling strip formed with eyelets to fit over the rings and arranged between each cover and the stack of leaves whereby to force the leaves forwardly upon the rings and compress their inner edges.

1. In combination with a loose leaf binder having covers connected by a back strip and split rings supported by the back strip for receiving and retaining loose leaves in place between the covers, of a plurality of comparatively narrow strips having eyelets along their longitudinal center to fit over the rings whereby the strips may be arranged between each cover and the stack of leaves, said strips adapted to maintain the leaves forwardly upon the rings, and to be parallel 10 with the leaves only when the binder covers are open.
